Answer:
About 25 kPa
Explanation:
Pressure decreases with height above sea level.
The calculation is rather complicated, so I will refer to the figure below.
It shows that the pressure at 10 km is about 25 kPa.
1,6,1,2 that should be the answer
Answer:
See explanation
Explanation:
The atomic number refers to the number of protons in the nucleus of an atom. We identify an element by its atomic number.
When the atomic number of an atom of an element is changed, we have changed the identity of that atom and transformed it into an atom of a different element.
For example, if we add a proton to a sodium atom, we create a magnesium atom. If we remove a proton from a sodium atom, we create a neon atom.
I believe the correct answer from the choices listed above is option B. The stair-step line between the pink squares and the yellow squares separates the metals <span>from the nonmetals. Hope this answers the question. Have a nice day.</span>
The alcohol has an oxygen atom single-bonded to hydrogen and single-bonded to a carbon-containing group.
<h3>What is alcohol? </h3>
Alcohol is defined as the organic compound which is derived from an hydrocarbon by replacing one hydrogen by hydroxyl group(—OH).
The general formula of alcohol is ROH.
where, R is the alkyl group.
The first member of alcohol is ethanol.
<h3>Physical properties of alcohol</h3>
- Alcohols are colourless.
- They give a sweet smell except for glycerol and few lower alcohols.
- They are flammable and produce a blue flame on burning.
- They don't produce any kind of smoke while burning.
- Alcohol are liquid at room temperature.
Thus, alcohol is an organic compound which contain an oxygen atom which is single-bonded to hydrogen and single-bonded to a carbon-containing group.
